# --description--

Align your `.header` text in the center. Make the text uppercase using the `text-transform` property with `uppercase` as the value.

Give it a padding of `32px` on all sides. Set the background to `#0a0a23` and the text to `#fff` as the color values.

Add a `border-bottom` with `4px solid #fdb347` as the value.

# --hints--

```js
assert.exists(new __helpers.CSSHelp(document).getStyle('.header'));
```

assert.equal(new __helpers.CSSHelp(document).getStyle('.header')?.textAlign, 'center');
```

```js
assert.equal(new __helpers.CSSHelp(document).getStyle('.header')?.textTransform, 'uppercase');

```
